Question

Solve the given equations by using method of elimination by equating the coefficients.
3x-4y=1
4x-3y=6

Answer 1

Answer:

x=3: y=2

Step-by-step explanation:

step 1: make the coefficients of x equal; multiply first equation by 4 and second equation by 3.

thus, equation 1*4=12x-16y=4

thus equation 2*3=12x-9y=18

                             -        +    -

                                      -7y=14

                                        y=2

step 2 and 3 : on subtracting

step 4: 3x-4y=1

            3x-4(2)=1

            3x=9

              x=3
